mass PREVENTER. I

. Application filed April 29, 1926. Serial No. 105,461.

This invention relates to smash preventers for looms of that type notequipped with brakes, and has for one of its objects the provision. of adevice of this character which shall be adapted to effect the throwingoff of the shipper and the stopping of the lay whenever the respectiveshuttle boxes simultaneously contain a shuttle.

A further object of the invention the provision of a device of thecharacter stated which can be readily applied to the breast beam and layof a loom without making any alterations in these or the other parts ofthe loom.

With the foregoing and other objects in View, theinvention consists ofthe novel construction, combination and arrangement of parts hereinafterfully described and claimed, and illustrated in .the accompanyingdrawings, wherein: u i r Figure 1 is a top plan view illustrating theapplication of the smash preventer to the breast beam and lay of aloom,

Figure 2 is a sectional view taken on the Figure 7 is a sectional viewtaken on the vertical plane indicatedby the line 7-7 of Figure 1. i

Corresponding and like parts are referred to in the followingdescription, and designated in the several views of the accompanyingdrawings, by similar reference characters. I

In the drawings. 1 designates the breast beam, 2 the lay and 3 theshuttle boxes of a loom. vThe rear walls and swells or binders of theshuttle boxes 3 are designated 4 and 5,

respectively. .As these parts are of v well known construction a furtherdescription thereof is deemed unnecessary y In accordance with myinvention, a shaft Storming a part ofthe shipper controlling mechanismof the loom, is supported from p the breast beam by bearing brackets 7 iarm 8 extending "a' rearward direction therefrom,'is secured: totheshaft 6 by set screw 9 and has 'an'arcuate rear endportion "8.,AlJOISlOIl spring 10 s mounted on'f the shaft 6 and is connected at itsends to one of ]-the bearing brackets 7 and a collar 11 mounted ontheshaft and secured thereto by a set screw 12. Thespring 10 tends torotate the shaft 6 in a direction to exert a constant upward pull onthe, arm 8. i A bracket 13 having a rearwardly extending horizontalmember 13) and a vertical member13 is sec-ured to'the breast beam 1 forvertical adjustment with respectthereto by screws 14-. which engage thebreast beam and passwthrough vertical slots in the bracket member'13". Avertically disposed arcuate lever 15'isconnectejd at itslower end to thebracket-member 13. for movement about a horizontal axis 16, and isprovided intermediate its ends with a horizontallydisposed pinjl7which'conta-c-ts with theupper convex edge of the [curved endportion8 ofthe lever 8. Thelever 15 is limited'in its upward movementby a stop 18and in its downward-movement by a stop 18 the stops being carried by andextendinghorizontally from the bracket member 13. Alatch 19 is pivotedintermediate its ends as at 20 to 'the upperportion of the lever 15, andits upper free end is yieldingly supported above the upper free end ofthe lever 15 by a spring 21. The movement ofthe latch 19in an up warddirection under the influence of the spring 21 is limited by a shoulder21 'formed on the lever 15 in position for engagement by the lower freeend, oflthe latch.

A shaft 22 carrying rearwardly extending daggers 28, is supported fromthe breast beam 1 by bearing/brackets 24. A rear- 7 wardly directed arm25v is secured to the shaft22 by a set screw 26, and is connected to thelever 15 by an elbow lever 27 and a link 28, ,The lever 27 is mountedupon the pivot'16 offthe lever 15, and an arm thereof is provided with ahead 29 having an arcuate slot30 through which passes abolt 31 carriedby the lever 15. The levers 15 and 27 are arranged in; parallelrelation, andthe stated connection between the same permits theirangular relation to be varied. The link 28 is engaged with one of aseries ofopenings 32 in the lever 27 and passes freely through the freeend ofthe arm 25, and a spring 33 is mounted on the link between anut'34 on the latter and between the arm 25; The

I ositions in which the i are shown in Fi ures openings 352 permit thelink 28 to be ad 2 and? lVhenthe lever is'actua't edin a downward andrearward direction it will,

due to the connection established between it and-the shaftb by means ofthe arm 8 and pin 17, and due'to the connection established between "itand the shaft 2'z2by the lever'27, link QS and arm 1'25, roclrtlieshafts in directions tothrow off the shipper and raisethedagge'rsQZlinto operative position, with the result that the loom willstop and the lay held against forward movement. lVhen the fleve'r15released, the spring 10 and daggers'23 will'rturn'the parts to theirnormal positions.

i Means for actuating the lever 15 whenever the respectiveshuttleboxes 3simultaneously contain a shuttle, is carrietl'by theilay 2 and comprisesa lever 35 extending forwardly and rearwardly of thelay and connected tothe under side thereof at a point intermediateits endsby movement abouta horizontal axis36. The pivot 36 is carriedby a bracket 37 whichisprovi'ded at the rear side of the lay2 in a vertically disposedboss'38. A vertical rod, 39. is slidably supported by the boss 38.spring 40 exerts a constant downwardpressure on the rod 39, and thedownwardmovement of the'ro'd is limited by anut ll. The-rod'39 is.pivotally connected as at liZ'to the rear end of the lever '35, and duethereto the latter is normally helfd in a-suhstantially horizontalposition. When the lever 35 is in this position, a'hook 43 carried bytheforward end of the'lever is supported out of the,path of the frontend'of the latch 19. A bar 44c extending longitudinally of the 'lay 2-ispivoted intermediate its ends to the rod 39 as at 45. The ends-of thebar M: pass through ertical .slotsttl in'brackets 47 which are. securedto ib elow the ends of the bar's It. Upwaiidly and rearwardly extendingarms'5l are secured at anddepend from the lay 2. Shafts 48 are supportedat the front side of-the-lay 2-by brackets 49. Downwardly andrearwar'dly extending arms 50' fixed attheir front ends .tothe shafts d8have their rear ends disposed their lower ends to the shafts4l-8 and areprovide d with angular upper terminals 52 which contact with the swellsor binders 5 of-the shuttle boxes 3. Springs 53 mounted on the shafts48; connected to collars 5% on the shafts and contacting with the underside -of the lay 2, exert constant downward pressure on the arms 50 andconstant rearward :grcrstops 55. 'from the lower e'dggesof the bracketmembers '56" and sem'e to guide the-free ends of 105 P essure -'on thearms "51 in :order to maintain the former out of contactwith the bar 44and the latter in contact with the swells or hinders "of the shuttleboxes 3.

When the arms 51 are simultaneously moved forwardly, as will occurwhenever a shuttle is in each of the boxes 3, the arms 50 a're'swung;upwardly. As the arms 50 are leverin a direction to depress'the frontend thereof and carry the hook 43 into the path of the fr'ont'end of thelatch 19. with the result thatthehookwill contact withthelatch duringthe backward.movement of the lay 2. This actuatest-heshipper throwingoff mechanism of wliichthe shaft '6 forms apart and as the@result'stopsthe-operation of theiloom.

At the same time the daggers 23 are raised into active position so'astoenable them to contact with stops 55 during the forward movement of thelay whereby to effect the V stopping of'the motion of the lay. Thedagger stops55 are removably secured mbraclr ets 56'by means of setscrews'57. The brackets56 are of angular formation presenting horizontalmembers 56 contacting with the under side of the lay 2 andconstitutingwear plates. brackets 56-contact withthe "front side o'f'thelay 2. Thebr-acket members 56 and 56 are conne'cted with their adjacentedges in relatively space'd relation by strap'lugs58 which are ofangular formation and which in conjunction with theifront edges of thebracket members 56 constitute supportsfor theTdag- Guides 59 extendforwardly the dangers 23 intoongagement with the stops'55-when thedangers are in raised or active position. The' brackets 56 are securedinplace by screws 60.

From the foregoing description, taken in connection with the acconipanying drawings, it-should be apparent'that the smash preventer willnot stop'the loom duringthe normal operation thereof, that it will imme--diately'throw olfthe shipperwhenever the respective shuttle boxessimultaneously contain a shuttle. and that it will at the same time stopthe movement of the lay. lVhile I have described the principle ofoperation of the invention. together with the structure 129 whichI nowconsider to be the' best embodinent thereof, I desire to have. itlunderstood that the dev1cesh0wn1s merely illustrative and that suchchanges may be made when (lBSlIQd as are within the scope ofthejinvention asclaimed.
